Re: [osg-users] How to get Center Parameter of CameraManipulator

Hi Ben
If I remember correctly getHomePosition() doesn't refer to the camera 
dynamic(t) view center but to the static(t) center of the scene...
Cheers

Hi,
After setCameraManipulator for my viewer i can get the Eye parameter of camera 
but cannot get the Center parameter to get the point of my camera looking at. 
How to get this value?

Here is the way i get the Eye parameter:


Code:
osg::Matrixd mt = _viewer->getCameraManipulator()->getMatrix();
Vec3d eye = mt.getTrans();





Thank you!

Cheers,
duc

Vec3d eye = mt.getTrans();





Thank you!
